## Создание `websocket` { #create-a-websocket }

Создайте `websocket` в своем **FastAPI** приложении:

{* ../../docs_src/websockets/tutorial001_py39.py hl[1,46:47] *}

/// note | Технические детали

Вы также можете использовать `from starlette.websockets import WebSocket`.

{* ../../docs_src/first_steps/tutorial001_py39.py hl[7] *}

Это функция на Python.

**FastAPI** будет вызывать её каждый раз, когда получает запрос к URL «`/`» с операцией `GET`.

В данном случае это асинхронная (`async`) функция.

---

Вы также можете определить её как обычную функцию вместо `async def`:
